Abstract

Abstract A control device for applying balanced forces to a pair of servient mechanisms. The control device has a control shaft mounted for rotation and axial translation in a housing. A pair of force-transmitting devices in the form of a push-pull control cables operatively connect the control device to the corresponding servient mechanisms, which may be located remotely of the control device. The control device has a pair of throw members in the form of bellcranks rotatably mounted on the housing for applying compressive or tensile stresses to the core of each push-pull cable. The control device also has a pair of link arms. One end of each link arm is operatively connected to a corresponding bellcrank by a universal joint spaced radially of the control shaft. The opposite end of each link arm is operatively attached to a lever arm, also by universal joints, and the lever arm is affixed to the control shaft for movement therewith. This second pair of universal joints is preferably also spaced radially of the control shaft in order to preclude interference between the two link arms and the control shaft or the housing, particularly as the latter moves through its rotational range. In any event, the second pair of universal joints may not be located in a common plane with both the control shaft and the first pair of universal joints and at the same time be spaced at the same radial distance from the control shaft as the first pair of universal joints if all the objectives of the present invention are to be achieved.

Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 95 words
A control device for applying balanced forces to a pair of servient mechanisms by a pair of force-transmitting means connected respectively therebetween comprising, a housing, a throw member for each force-transmitting means, each throw member being movably mounted on said housing, a control shaft mounted in said housing for rotation and axial translation, a pair of link means having opposed ends, one end of each link means connected to a corresponding throw member at a location spaced radially of said control shaft, the other end of each link means operatively connected to the control shaft.
Claim 2
Dependent Claim 95 words
A control device for applying balanced forces to a pair of servient mechanisms by a pair of force-transmitting means connected respectively therebetween comprising, a housing, a throw member for each force-transmitting means, each throw member being movably mounted on said housing, a control shaft mounted in said housing for rotation and axial translation, a pair of link means having opposed ends, one end of each link means connected to a corresponding throw member at a location spaced radially of said control shaft, the other end of each link means operatively connected to the control shaft.
Claim 3
Dependent Claim 28 words
A control device, as set forth in claim 1, in which the operative connection of each link means to the control shaft is accomplished by first universal joints.
Claim 4
Dependent Claim 40 words
A control device, as set forth in claim 2, in which each throw member is in the form of a bellcrank rotatably mounted on said housing and in which second universal joints connect each link means to the corresponding bellcrank.
Claim 5
Dependent Claim 31 words
A control device, as set forth in claim 2, in which a lever arm is secured to said control shaft for mounting said first universal joints radially of said control shaft.
Claim 6
Dependent Claim 29 words
A control device, as set forth in claim 4, in which said lever arm is disposed to mount said first universal joints on opposite sides of said control shaft.
Claim 7
Dependent Claim 29 words
A control device, as set forth in claim 5, in which said throw members are mounted on said housing to be disposed on opposite sides of said control shaft.
Claim 8
Dependent Claim 41 words
A control device, as set forth in claim 6, in which said throw members are each in the form of a bellcrank rotatably mounted on said housing and in which second universal joints connect each link means to the corresponding bellcrank.
Claim 9
Dependent Claim 63 words
A control device, as set forth in claim 1, in which the ends of said link means operatively connected to said control shaft are spaced a greater radial distance from said control shaft than the ends of said link means connected to said throw member and in which a thrust stabilization means is operatively connected between each said throw member and said housing.
Claim 10
Dependent Claim 47 words
A control device, as set forth in claim 8, in which a universal joint connects each said link means to the corresponding throw member, said stabilization means comprising, a post portion on each said universal joint, and flange means on said post portion for engaging said housing.
Claim 11
Dependent Claim 47 words
A control device, as set forth in claim 9, in which said housing has plate means, a pair of slot means in said plate means, each said post portion passing through one of said slot means and said flange means engaging opposite sides of said plate means.
Claim 12
Dependent Claim 27 words
A control device, as set forth in claim 10, in which each throw member is in the form of a bellcrank mounted for rotation about an axis.
Claim 13
Dependent Claim 35 words
A control device, as set forth in claim 11, in which said slot means is arcuate with respect to the axis about which the bellcrank to which the post portion received therein is operatively connected.
